What is the difference between “when the operating system shuts down” and “when the kernel shuts...

Reading one of Stephen's excellent replies, I was wondering what differences are between




When the operating system shuts down. ...




and




When the kernel shuts down, ... (... I’m considering that the variant which uses an external command to shut down isn’t the kernel)




?



Is "the variant which uses an external command to shut down" "when the OS shuts down" or "when the kernel shuts down"?



What does "I’m considering that the variant which uses an external command to shut down isn’t the kernel" mean in other words?



Does system call reboot() reboot the OS or kernel?



Does command reboot reboot the OS but not the kernel?



Thanks.

  • Deleting the reference and link to the reboot() documentation, the most fundamental part of the sentence, from the last quote is utterly inexplicable to me.

  • That's because I don't quite understant what the original means. If you do, thank you in advance to tell me what that means.

The post you have quoted from actually says this:




When the kernel shuts down, or reboots, it doesn’t care about processes and doesn’t kill them (see reboot() for details; I’m considering that the variant which uses an external command to shut down isn’t the kernel).




Your selective editing has spliced together unrelated sentences to create a false impression.



The part you have kept (from after the semicolon) relates to the part immediately before the semicolon (which you have deleted). That is, the variant of reboot() which uses an external command to shut down (LINUX_REBOOT_CMD_RESTART2, in the documentation, which was linked) is being excluded from consideration for Stephen's purposes.



The first quote is not relevant.
